Title: Method for modifying surface
Inventor: OKANIWA SHIGERU
IPC: C21D1/62
Filed: 1991-07-02
Abstract: PURPOSE:To improve the adhesion, surface lubricity and erosion resistance of a nitriding layer, in a method for irradiating the surface of a substrate after nitriding treatment with a laser beam, by regulating the strength of the laser beam to specified one. CONSTITUTION:A nitriding layer 40 formed on the surface of a substrate 10 such as a tool steel is irradiated with a laser beam by irradiation power by which the matrix does not transformed into martensite and nitrides dispersed in the nitriding layer are parted. In this way, slender acicular nitrides dispersed in the diffusion layer 20 are converted into thickly and shortly spheroidized nitrides 23, and the density gradient between the nirides 23 and the matrix 24 is also relaxed. Moreover, many fine cracks which have been generated on the nitriding layer 30 disappear, by which the nitriding layer improved in surface lubricity and having high resistance to wear, particularly to erosion caused by molten metal or high temp. materials can be obtd. Thus, dies for casting, dies for extruding, dies for forming, tools or the like having a long life can be obtd.

Title: Line switching system
Inventor: IKAWA FUMIHIRO
IPC: H04B1/74
Filed: 1989-07-20
Abstract: PURPOSE:To prevent an allowable distance between the repeater of a terminal station reduced by providing a monitor switching means to switch and send a bipolar signal after amplification bi-sected with a hybrid transformer to either a prescribed line in current use or a spare line. CONSTITUTION:An amplifier means 200 amplifies to double the bipolar signal sent to a prescribed line 1-1 in current use. The hybrid transformer 300 bi-sects the bipolar signal after amplification sent from the amplifier means 200, and sends one to the prescribed line 1-1 in current use, and sends the other to a spare line 2, The monitor switching means 400 monitors the operating power source of the amplifier means 200, and when power failure occurs in the operating power source, the bipolar signal switched and outputted from a switching means 100 is switched and outputted to either the prescribed line 1 in current use or the spare line 2. Therefore, the bipolar signal sent to the line in current use can hold the same signal level as that of the bipolar signal sent to another line in current use. In such a way, it is possible to prevent a possibility to reduce the distance between the repeater of the terminal station to a half.

IPC: H01L21/8224
Filed: 1987-07-27
Abstract: PURPOSE:To obtain a vertical bipolar transistor in which the width of a base region can be freely altered by etching a predetermined region for separately diffusing in advance before an isolating region is formed. CONSTITUTION:An N<+> type buried layer 2 is formed on a P-type silicon substrate, a P<+> type buried layer 3 to become the collector region of a vertical PNP transistor is formed on the layer 2, and a P<+> type buried layer 4 to become an isolating region is simultaneously formed on a P-type silicon substrate 1. Then, an N-type epitaxial layer 5 is grown on a whole surface, an oxide film 6 which becomes a diffusing mask of an isolating diffusion (P<+>) from above is formed, and an oxide film on the diffused region from above is removed by patterning by means of a predetermined photoetching technique. The mask material (photoresist layer 7) used for patterning is utilized as it is, and an N-type epitaxial layer to become the isolating region is etched in a predetermined amount. This setup suppresses the upward diffusion into the epitaxial layer of the P<+> type buried layer to a small value. After a P<+> type isolating region 8 is formed, a base diffusion and an emitter diffusion are performed.

Abstract: PROBLEM TO BE SOLVED: To position a prepared hole accurately on every crankshaft with the dispersion of a prepared hole within tolerance in premachining by providing a positioning pin with a centering means for adjusting the center of the prepared hole to a machining axis. SOLUTION: In case the diameter of a positioning pin 8 is smaller than a prepared hole (h), a pair of ball plungers 13, 13 come in contact with the internal wall of the prepared hole (h) to make spring energizing force the same, so that the center of the prepared hole (h) can coincide accurately with the axial center of the positioning pin 8. The axis of the positioning pin is previously made coincide with the axis of a machining tool. A temporary receiving part is retreated to pull the positioning pin 8 from the prepared hole (h), and at the same time, the machining tool is advanced from an opposite direction to machine the prepared hole (h). Centering is therefore performed correctly, so that machining can be performed with accuracy.
